Correct Answer: 8

Solution and Explanation

The power of 10 is not counted. In 50000.020: the digits are 5, 0, 0, 0, 0, 0, 2, 0.
The zeros between 5 and 2 are significant (they lie between non-zero digits), and the trailing zero after the decimal point is significant.
Total = 8 significant figures.
